[Libusb-win32-devel] Antwort: [RMX:##] Re: LibUsb_win32 license question

[Stephan M. <Ste...@ia...>]

libusb.lib is *not* a static version of libusb0.dll it's just 
an import library that loads the DLL at runtime.

Apart from that I don't know (I'm no LGPL expert)
whether or not its legal to *statically* link a proprietary
application with a LGPL library.
